Updating from PointBase to Derby

I recently bought Sams Teach Yourself J2EE to learn the Enterprise Edition
from scratch. The book has one main application that it develops. The
problem is it uses the PointBase database which Sun replaced with Derby on
December 5th. I am unable to get started, because being new to the EE, I do
not know how to replace the following two lines with the Derby equivalent:

private static final String driver = "com.pointbase.jdbc.
jdbcUniversalDriver";
private static final String protocol = "jdbc:pointbase:server://localhost/sun-
appserv-samples,new";

I think if I can get past that, I can get started with the book. Has anyone
else encountered this? Any help would be appreciated. Thanks.
